I think that I'd concur that new gamers might be mystified regarding the first player marker when it is first mentioned on page 10. There really needs to be something there. This could be as simple as adding "Randomly assign the first-player marker to a player." to the Starting Positions section.
I think slightly repositioning and tightening the top white space on the Starting Positions diagram would give enough space for a short sentence like this.

As far as the reference on page 24, just an observation: the symbols in the damage section don't pop very well. It takes some visual searching (which equates to game time) to find the icon you're looking for. They just don't stand out very well. Compare them visually to the Dice Icons and you should be able to see what I mean.
